4 Claims. (Cl. 52--99) Our invention relates to means for mountingmetallic members in a brick mould and is a division of our applicationSerial No. 57,545, filed September 21, 1960, now Patent No. 3,109,702,patented November 5, 1963, on Method of Co-Moulding Brick.

In making brick that comprises basic refractory material and metal, ithas been found highly desirable to provide for the even distribution ofthe metal in the body of the brick and to avoid the exposure of themetal on the surface of the brick. Furthermore it has been found highlydesirable to distribute the metal in the brick in a uniform mannerthroughout the body of the brick. The uniform and even distribution ofthe metal in the brick has been found to reduce the tendency of thebrick to crack along certain lines upon being heated to furnacetemperature, which cracking has been found to be caused, at least inpart, by uneven distribution of metal in the body of the brick.

It has been further found to be desirable in moulding a brick of theabove referred to character, in the usual machine provided for mouldingsuch brick, that plates be used for the metal in the brick, which arelocated in a position such that the same extend longitudinally of themould and perpendicularly to the direction of movement of the plungersthat act to compress the refractory material in the brick. The metalused in a brick of this character must be oxidizable readily under theheat of the furnace in order to combine with the refractory material ofthe brick to provide a strong structure for the wall or roof in whichthe brick is utilized. By avoiding exposure on the sides of the brick ofthe metal members that are inserted in the body of the brick it ispossible to provide a tighter wall or roof in building the structure inwhich the bricks are used.

It is accordingly a purpose of our invention to provide means formounting metal plates in a mould for a brick of the above mentionedcharacter in such a manner that said plates are spaced from the top,bottom and sides of the brick in the mould when the compressingoperation on the refractory material in the mould is completed. Thismakes it necessary to provide means for spacing the metal members thatare to be incorporated in the brick from the side walls of the mould andfrom the bottom plunger of the mould, as the filling of the mouldproceeds with the refractory material, and to continue this holding ofthe metal members in this position until the mould is filled completelywith the amount of refractory material required to form the brick. Themounting of the metal members in the mould must be in such a positionthat when the mould is filled the refractory material will extend abovethe top edges of the plates, so that when the refractory material iscompressed by the plungers there will be refractory material betweenboth the top and bottom plungers and the metal inserted in the mould.

In order to accomplish this it is necessary that the holding means he ofsuch a character that it will be released as soon as the compressingoperation begins so that the bottom plunger will not move the platesupwardly in the mould out of the position originally assumed there-States atnt by. By mounting said metal members midway between the topand bottom of the mould cavity all movement of the refractory materialduring the compressing action of the plunger-s is toward thelongitudinal middle of said metal members, from the opposed longitudinaledges thereof. In order that the metal members be properly spaced fromeach other and from the sides of the mould, means is provided forholding the same away from the sides of the mould and from each other ina definite fixed position during the mould filling operation.

In order to get the even distribution of the metal throughout the massof the refractory material in the moulded brick, it is highly desirableto maintain said plates in parallel relationship throughout the mouldingoperation so that these plates will remain in such parallel relationshipin the finished brick. It has been found that while it is highlydesirable to maintain the plates in spaced relation from the sides andbottom of the mould and in predetermined spaced relation to each otherduring the filling operation, that if the means for holding the same inthis position are not released during the compressing operation, therewill be warping or distortion of the plates out of their parallelrelationship. In order to avoid this, frangible or disruptable means isprovided for spacing the plates from the sides and bottom of the mouldand from each other so that as soon as any appreciable pressure isapplied thereto the same will rupture and release the plates from eachother and from the sides and bottom of the mould so that the movement ofthe refractory material under pressure will not cause any movement ofthe plates out of their parallel relationship due to the action of thespacing means thereon during the compressing operation.

It is a purpose of our invention to provide means for holding the platesin position in a mould by means of wire spacing members, which wires aresecured to the plates and are of a hardened character so that if thesame are provided with weakened portions, these weakened portions willreadily rupture in order that the spacing wires will separate or rupturebetween the plates and between the bottom of the mould and sides of themould and the plates.

It is particularly desirable, in the machine moulding of such refractorymembers, that it be possible to merely drop the metal members with theirspacing means into the mould during the operation of the machine, whenthe plungers have been retracted and the mould cavity is empty. While aslight endwise movement can be utilized, in the insertion of a metalinsert during the inserting operation, in order to locate it lengthwiseof the mould, by engaging the ends of certain of the metal members withthe end walls of the mould, preferably such endwise movement of themetal insert after being placed in the mould is to be avoided so as toavoid any possibility of injury to the operator of the machine by themechanism, should he take too much time in locating the metal insert inthe mould.

It accordingly is another purpose of our invention to provide a metalinsert, of the above referred to character, with spacing means that isof such a character that it will space the metal members both from theend walls and the side Walls of the mould, so that all that is necessaryis to drop the insert into the mould, this result being obtained byproviding diagonally or obliquely extending spacing members, extendingfrom certain of the plates toward the corners of the mould, saidobliquely extending spacing members being of the same character as theother above referred to spacing members .and provided with weakenedportions for the same purpose as above referred to.

ther objects and advantages of our invention will appear as thedescription of the drawings proceeds. We desire to have it understood,however, that we do not intend to limit ourselves to the particulardetails shown or described, except as defined by the claims.

FIG. 7 is a transverse sectional view through the mould, showing thesame after the metal insert has been placed therein and the mould cavityfilled with the refractory material.

FIG. 8 is a similar view, showing the position of the parts after thecompressing of the refractory material has been completed.

FIG. 9 is a view similar to FIG. 1 of a modification, and

FIG. 10 is a fragmentary view partly in transverse section and partly inelevation of the form of the invention shown in FIG. 9, on an enlargedscale.

Referring in detail to the drawings, in FIGS. 1, 3, 4 and FIG. 7, themetal insert is shown in the condition in which it is placed in themould, and preferably comprises a pair of outer plates 11 and a slightlyshorter central plate 11. Said plates 11 and 11' are to be located inthe finished brick in parallel relationship in uniformly spaced relationto each other, and are preferably spaced so that the plates 11 arespaced the same distance from the side walls of the mould cavity as thecentral plate 11 is spaced from the adjacent members 11. The mould isprovided with side walls 12 and end walls 13 and has its bottom wallformed by means of a plunger 14, which is slidable between the end walls13 and side walls 12. It is desirable to locate the plates 11 and 11' sothat the same are located midway between the plunger 14 and the top 15of the mould cavity provided between the walls 12 and 13 and the plunger14. This is desirable because it has been found that the movement of thematerial is from the top 15 and the plunger 14 toward the verticalmiddle of the mould, and by locating the plates so that the middle ofsaid plates is located in this vertical middle plane of the mouldcavity, the movement of the material between the members 11 and 11'during the compressing action will be entirely toward this mid-line withno movement at the longitudinal middle of the plates at all. This isdesirable, as, in that way, the forces applied to the plates are suchthat they are not moved out of the position that they have been placedin prior to the compression of the refractory material in the mould.

In order to accomplish this location of the plates with respect to theside walls and end walls of the mould and the plunger 14, frangible ordisruptable members are provided for holding the plates spaced from theends and sides of the mould and from each other, as well as from theplunger 14. Said means preferably comprises a pair of wire spacingmembers having transverse portions 16, which are secured to the bottomlongitudinal edges of the ribbon-like metal members 11 and 11 bywelding, and which have downturned end portions 17 that form legs thatengage with the top surface of the plunger 14.

Said wire spacing members are made of a hard wire that is somewhatbrittle so that it will readily break under a bending stress. In orderto facilitate such breaking, transverse notches 18 are provided in thetransvers portion 16 of said wire members between the ribbon-like member11 and the members 11, these notches being in the upper side of thetransverse portion 16, and transverse notches 19 are provided betweenthe ribbon-like members 11 and the bends 20 in said wires connecting thetransverse portion 16 with the legs 17. The notches 19 are on the underside of the transverse portion 16 of these wires.

In order to space the plates secured in spaced relation to each other bymeans of the transverse portions 16, in spaced relation to the sides 12and the ends 13 of the mould, and to further provide spacing meansconnecting said members 11 and 11, the wires having the transverseportions 21 are provided, which are engaged with the bottom edges of theplates 11 and 11' in the manner shown in FIGS. 1, 3, 4 and 7. The samekind of wire is used for these wire members as for the previouslydescribed wire members that have the legs 17, and said wire members arewelded to the bottom edges of the plates 11 and 11 where the transverseportions 21 thereof intersect the same. Said wire members are furtherprovided with obliquely or diagonally extending portions 22, that extendtoward the corners of the mould Where the ends 13 and sides 12 thereofmeet, being of such length as to fit loosely etween the end walls 13 andthe side walls 12. Said transverse portions 21 and obliquely extendingportions 22 are connected by means of bends 23. Transverse notches 24are provided in the top sides of the transverse portions 21 to provideweakened places therein, and transverse notches 25 are provided betweenthe bends 23 and the plates 11 on the under sides of the transverseportions 21 adjacent said bends 23.

In the use of the metal insert shown in FIGS. 1, 3, 4, and 7, the insertis merely dropped into the mould with the leg portions 17 downwardly,after the plunger 14 has been retracted and the mold is empty. Theplates 11 and 11' are then in the position that it is desired to havethe same in the finished brick after the plunger 14 and the upperplunger 26 have acted on the contents of the mould cavity. With themetal insert in the position shown in FIGS. 3 and 4 in the empty mould,the mould is filled to the top 15 thereof with the refractory material27, that is to form the body portion of the brick. After the mouldcavity has been entirely filled with said refractory material theplungers 14 and 26 are moved toward each other, and as soon as theplunger 26 enters the mould cavity compression of the refractorymaterial commences. It will be noted that the plunger 26 is providedwith a projection 28, which is usually provided on a plunger of thischaracter for forming a hanger recess 29 in the finished brick, which isshown in FIG. 5. In order that this projection 28 will enter therefractory material without interference on the part of the metal to beco-moulded with the brick, the inner plate 11' is made shorter than themembers 11 at one end of the insert so that the recess formingprojection 28 will avoid the same.

When compression of the refractory material 27 by means of the plungers14 and 26 begins, the legs 17 will tend to be moved upwardly by theplunger 14, but due to the resistance of the refractory material 27 tosuch movement, the legs 17 will be separated from the transverseportions 16 by rupture at the notches 19 and will be carried upwardlywith the plunger 14 without any appreciable movement of the remainingmetal structure, such as the plates 11 and 11'. As movement of theplungers 26 and 14 toward each other in the mould cavity continues, thepressure on the horizontally extending portions 16, 21 and 22 of thewire members will gradually increase, and due to the weakened portions18, 24 and 25, said wire members will rupture at these weakened portionsfreeing the plates 11 and 11 from each other and from the walls of themould.

Due to the character of the wire used and the weakened portions providedtherein, this rupture of the wires and breaking of the connectionsbetween the plate-like members will take place before sufiicient forcehas been exerted by the compression of the refractory material on thehorizontally extending portions of the wires to cause any tilting orwarping of the plates out of parallel relationship to each other and tothe side walls of the mould and thus in perpendicular relationship tothe faces of the plungers 14 and 26.

As the wires that connect the plates with each other and space them fromthe side walls and end walls of the mould are located below the verticalmiddle of the mould, there will be some movement of the broken offportions of the wire members with the refractory material in an upwarddirection in the mould, which will result in the wire sections thatremain being bent somewhat upwardly at the ends thereof remote from theplates, in the case of the transverse portions 16 and 21, as shown at inFIGS. 2 and 8, the free ends, constituting the leg portions 17, and theobliquely extending portions 22 assuming substantially the positionshown in FIGS. 2 and 8 as the plungers 14 and 26 reach their finalposition for completing the compression of the refractory material 27 asshown in FIG. 8.

The finished brick is shown in FIGS. 5 and 6 and it will be seen thatthe ends 31 of all the plates 11 and 11' are spaced from the ends 32 ofthe body portion of the brick with the wire legs 17 embedded in thebrick in substantially the position shown, as are also the obliquelyextending portions 22 and the fragments of the connecting portions 16and 21, which are designated by the numeral 33 in FIGS. 5 and 6. It willalso be noted upon reference to FIG. 5 that the top and bottomlongitudinal edges 34 and 35 of said plates are spaced inwardlysubstantially the same distance from the side face 36 and the side face37 of the brick, these being the wide side faces of the brick which wereuppermost and lowermost in the mould, but which would ordinarily bevertical side faces when the brick is hung from the hanger that extendsinto the cavity or socket 29. Also, upon reference to FIG. 6, it will benoted that the plates 11 and 11 are spaced substantially the samedistance from each other as the Plates 11 are spaced from the sides 38and 39 of the brick, which are the narrow longitudinal side facesthereof, which constitute the vertical side faces during the mouldingoperation.

Due to the position of the plates 11 and 11' in the mould during thecompressing operation, the movement of the refractory material 27 willbe from the plungers 14 and 26 parallel to the faces of the plates 11and 11 toward the longitudinal middle of these faces, and inspection ofsaid plates after the compressing operation has been completed, showsthere is substantially no movement of the refractory material whatsoeveralong said faces at the center line thereof. Since the wire connectingmembers or spacing members are ruptured at substantially the beginningof the compressing operation, these do not in any manner interfere withthe compression of the re fractory material nor does the compression ofthe refractory material in any manner affect the position or shape ofthe plates 11 and 11', as the compression of the refractory material isparallel to the faces of said plates and the forces acting thereon areprincipally parallel to said faces, with no connections between theplates extending tranversely to the direction of movement of thematerial under compression, which would exert torsional forces on theplate-like or ribbon-like members.

In FIG. 9 a modified form of metallic insert is shown, in which theplates 111 are all shown as being of equal length, as no hanger recessis to be provided in this brick. Only one pair of wire spacing membersis provided in this form of the invention, said spacing members havingthe transversely extending portions 16 having the notches 18 therein andhaving obliquely extending ends providing the leg portions 17' connectedwith the portions 16 by means of the bends 2t and having the notches 19therein for the same purpose as previously described, said transverseportions 16 being welded to the plates 111. However, instead ofproviding the members having the diagonally extending end portions 22,the legs 17 extend obliquely both transversely and vertically of themould so as to space the metal plates 111 not only from the bottomplunger 14 but also from the side and end walls of the mould.

Thus the insert shown in FIGS. 9 and 10 will be spaced from the side andend walls and the bottom plunger by engagement of the ends of the legs17 with the end corners of the mould at the top face of the plunger 14.The operation of the insert shown in FIGS. 9 and 10 is the same as thatshown in FIGS. 1 to 8 inclusive, and the compression of the refractorymaterial will cause the rupture of the wire members at the notchesprovided therein, in the same manner as previously described, so as tofreely mount the plates 111 in the body of refractory material as it isbeing compressed, it being, of course, to be understood that the metalinsert is first placed in the mould cavity, after which it is filledcompletely with the refractory material in the same manner as has beendescribed in connection with FIGS. 1 to 8, before the plungers areactuated to compress the said refractory material and while the members111 are held in position midway between the top and bottom of the mouldcavity and in the desired spaced relation to each other and to the sideand end walls of the mould cavity.
